purge-cluster: check if rbdmap exists 

When running `infrastructure-playbooks/purge-cluster.yml` twice, it fails the
second time on the `ensure rbd devices are unmapped` task, because `rbdmap`
isn't installed anymore at that point.

This commit adds a check that ensures `rbdmap` is available, and skips the
`ensure rbd devices are unmapped` task if it isn't.
